How to add new RBLs to cpanel Exim

August 11th, 2009 No Comments   Posted in System Administration, Web Servers Security, Web hosting, cpanel

More then a year ago, cPanel added a future to the Exim Configuration Editor for everyone to easily select from two RBLs (spamhaus.org and spamcop.net) that can be used to filter most of the SPAM that a server receives. While this has been great for most of us (enabling a RBL is a simple as selecting a check box in WHM and pressing the Save button), there are a few admins that would have liked to add additional RBLs to the list that Exim uses to filter SPAM emails. RBLs like dnsbl.njabl.org, list.dsbl.org, dul.dnsbl.sorbs.net, etc. are all considered useful by many, but not included by default.

The question is how can such a RBL be added to Exim ?
Well it’s not that hard !
First you will have to login to your server using ssh.
After a successful login:

  1. Change directory to /usr/local/cpanel/etc/exim/acls/ACL_RBL_BLOCK
